Syntax

valX = dec2mat(lmisys,decvars,X)

Description

Given a valuedecvarsof the vector of decision variables,dec2matcomputes the corresponding valuevalXof the matrix variable with identifierX. This identifier is returned bylmivarwhen declaring the matrix variable.

Recall that the decision variables are all free scalar variables in the LMI problem and correspond to the free entries of the matrix variablesX₁, . . .,X_K. Since LMI solvers return a feasible or optimal value of the vector of decision variables,dec2matis useful to derive the corresponding feasible or optimal values of the matrix variables.
